With the help of a good number of members , (Thank You!), I have been able to purchase all needed replacement parts for the LH hub on my 1050 transmission. Now that I am ready reassemble the transmission I am going by the exploded parts diagram and see that the 2 shims (PN's 1716498 & 1716499) say "as required". What is the measurement that will determine how many shims are needed? When I disassembled the hub there were 4 shims in there, 2 were damaged. Since I am putting in new parts can I assume that all 4 shims are not needed? But again, how do I determine that? I have a Bolens bulletin, (service bulletin #1-67), that describes how to adjust the "Rear axle end-play", but it does not address the number of shims needed. Am I overthinking this? Should I just put in the .0125 and .005 shims as shown in the exploded diagram and do the rear end play adjustment and let it go at that? Any info would much appreciated!
